What is the better solution for waterproofing in showers?
We have 3'X3' shower on a slab level.
We have used Hydroment Gold Anti Fracture and waterproofing membrane on horizontal and vertical application. It is a latex base , paint application. Easy to use. We have received some comments that it will not hold back water as a traditional rubber membrane.
Reading specifications of the product we have learned that it meets American Specifications:ANSIA118.10 and supposed to be a good barrier.
Do you have any experience using this product? We have not installed tiles yet. Out tiles are 1/8" marble tiles.

Myself I never use the Hydroment, but I use similar product called Pro Red by c-cure, and I know the Hydroment brand are as good as the Pro Red, and it should do the job of waterproofing your shower with no problem.
I like those liquid rubber membrane waterproofing better then rubbers type or the other type of sheeting, Easy, cheaper, and save lots of labor time
